Description

Die Erfindung bezieht sich auf eine Schneefräse zum Anbau an einem Arbeitsgerät, wobei die Schneefräse eine Vorrichtung zum Anpassen der Ausrichtung von der Schneefräse mit ein oder mehreren Einstellvorrichtungen zum Einstellen der Neigung, Schwenkung, Seitenverstellung umfasst.The invention relates to a snow blower for attachment to an implement, the snow blower comprising a device for adjusting the alignment of the snow blower with one or more adjustment devices for adjusting the tilt, swivel, lateral adjustment.

Bei Schneefräsen besteht das große Problem, daß insbesondere bei Kurvenfahrten auch eine seitliche Bewegung der Schneefräse, die oftmals an einem Fahrzeug wie einem Traktor, Unimog oder dergleichen angebaut ist, auftritt.The big problem with snow blowers is that, particularly when cornering, the snow blower, which is often attached to a vehicle such as a tractor, Unimog or the like, also moves sideways.

Diese seitlichen Bewegungen führen dazu, daß der seitlich gelegene Schnee nicht mit der Fräse aufgenommen werden kann und die Kurvenfahr behindert.These lateral movements mean that the snow lying on the side cannot be picked up by the tiller and hinders cornering.

Gerade bei größeren Schneehöhen und festerem Schnee, die durchfahren werden müssen, stellt dies ein nicht zu vernachlässigendes Problem dar.This is a problem that should not be neglected, especially in the case of greater snow depths and firmer snow that have to be driven through.

In der Vergangenheit wurden deswegen auch Konstruktionen getestet, bei denen die Fräse seitlich offen ist, um auch dort den Eintritt von Schnee zu ermöglichen.In the past, therefore, designs were also tested in which the tiller is open at the side to allow snow to enter there as well.

Seitlich offene Fräsen bieten jedoch eine geringere Räumqualität, da auch Schnee seitlich herausfällt.However, tillers that are open at the side offer a lower clearing quality, since snow also falls out at the side.

Zudem besteht die Gefahr, daß feste Gegenstände und auch Eisklumpen unkontrolliert weggeschleudert werden.There is also the danger that solid objects and lumps of ice will be thrown away in an uncontrolled manner.

Eine andere Herangehensweise an dieses Problem war, daß durch mehrfaches Vor- und Zurückfahren die gefräste Gasse vor allem in Richtung der Kurveninnenseite verbreitert wurde um dann die eigentliche Kurve fahren zu können.Another approach to this problem was that the milled lane was widened by driving forwards and backwards several times, especially towards the inside of the curve, in order to then be able to drive the actual curve.

Beide Varianten sind nicht zielführend und weisen erhebliche Nachteile auf.Both variants are not effective and have significant disadvantages.

Aus der DE 2 156 321 A1 ist beispielsweise eine gattungsgemäße Schneefräse bekannt.From the DE 2 156 321 A1 is known, for example, a generic snow blower.

Die DE 20 2011 107 751 U1 beschreibt auch eine Kraftbegrenzungseinrichtung, welche jedoch von Hand vom Bediener zurückgesetzt werden muss. the DE 20 2011 107 751 U1 also describes a force limiting device which, however, has to be reset manually by the operator.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung vorzuschlagen, die ein direktes Kurvenfahren von Arbeitsgeräten mit Schneefräsen beim Fräsvorgang ermöglicht und zudem die Sicherheit der Vorrichtung erhöht.It is therefore the object of the present invention to propose a device which enables implements with snow cutters to drive directly around curves during the milling process and also increases the safety of the device.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the features of claim 1 .

Hierdurch kann die Schneefräse an die jeweilige Arbeits- bzw. Fahrsituation angepasst werden.This allows the snow blower to be adapted to the respective work or driving situation.

Mit Hilfe von Hydraulikzylindern kann die Einstellung auf einfache Art und Weise vorgenommen werden.With the help of hydraulic cylinders, the adjustment can be made in a simple manner.

Durch eine Kraftbegrenzungsvorrichtung sind Schäden vermeidbar, die andernfalls zum Beispiel beim Anfahren gegen feste Gegenstände auftreten würden. Durch die Kraftbegrenzungsvorrichtung kann zum Beispiel ein Wegkippen der Fräse ermöglicht werden. Oftmals wird auch das Abscheren von in der Fräse vorgesehenen Scherbolzen verhindert. Mit einem Überdruckventil wird eine effektive Kraftbegrenzungseinrichtung geschaffen.A force-limiting device prevents damage that would otherwise occur, for example when hitting solid objects. The force-limiting device can, for example, allow the tiller to tip over. Shearing of shear bolts provided in the milling machine is also often prevented. An effective force limiting device is created with a pressure relief valve.

Durch eine Nachführungseinrichtung kann eine automatische oder halbautomatische Einstellung der Fräse erfolgen.The milling machine can be adjusted automatically or semi-automatically by means of a tracking device.

Erfindungsgemäß ist es auch sehr vorteilhaft, wenn ein oder mehrere Drehpunkte für die jeweilige Bewegungsrichtung vorgesehen sind.According to the invention, it is also very advantageous if one or more pivot points are provided for the respective direction of movement.

Damit kann eine optimale Einstellung vorgenommen werden.This allows an optimal setting to be made.

Dabei hat es sich als sehr vorteilhaft erwiesen, wenn die Nachführungseinrichtung den Lenkwinkel des Arbeitsgerätes erfasst.It has proven to be very advantageous if the tracking device detects the steering angle of the implement.

Ebenfalls sehr vorteilhaft ist es erfindungsgemäß, wenn die Nachführungseinrichtung die Radstellung des Arbeitsgerätes erfasst.It is also very advantageous according to the invention if the tracking device detects the wheel position of the implement.

Mit beiden Varianten kann in Abhängigkeit zur gewünschten Fahrtrichtung eine Einstellung der Schneefräse erfolgen. Je nach Ausgestaltung des Arbeitsgerätes kann die eine oder die andere Variante zum Einsatz kommen.With both variants, the snow blower can be adjusted depending on the desired direction of travel. Depending on the design of the working device, one or the other variant can be used.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

Mit 1 ist in Fig. 1 eine Schneefräse bezeichnet, die an einer durch Vorderräder 2 und Hinterräder 3 angedeuteten Arbeitsmaschine 4 angebracht ist.With 1 is in 1 designates a snowblower mounted on a working machine 4 indicated by front wheels 2 and rear wheels 3 .

Mit der Fräse 1 wird in einer Schneeansammlung 5 eine Gasse 6 gebildet.With the tiller 1 a lane 6 is formed in a snow accumulation 5 .

Soll nun eine Rechtskurve gefahren werden, wie dies durch die Radstellung der Vorderräder 2 angedeutet ist, so muss die Fräse 1 ebenfalls nach rechts bewegt werden. Die seitliche Bewegungsrichtung 7 ist durch einen Pfeil angedeutet.If a right turn is now to be driven, as is indicated by the wheel position of the front wheels 2, the tiller 1 must also be moved to the right. The lateral direction of movement 7 is indicated by an arrow.

Dies ist aber gerade bei großen und festen, möglichst noch verharschten oder vereisten Schneeansammlungen 5 nicht möglich. Der Schnee in Begwegungsrichtung 7 bildet ein festes Hindernis und sorgt so dafür, daß die Kurve nicht gefahren werden kann.However, this is not possible in the case of large and solid accumulations of snow 5 that are as crusted or frozen as possible. The snow in the direction of movement 7 forms a solid obstacle and thus ensures that the curve cannot be driven.

Oftmals konnte man durch mehrfaches Vor- und Zurückfahren die Gasse 6 erweiteren und so eine Richtungsänderung erzielen.It was often possible to widen alley 6 by driving forwards and backwards several times, thus achieving a change of direction.

Dies ist jedoch zeitaufwendig und auch zusätzlicher Kraftstoffverbrauch ist nicht vernachlässigbar.However, this is time-consuming and additional fuel consumption is also not negligible.

Entsprechend der vorliegenden Erfindung ist nun die Fräse 1 über ein Drehgelenk 8 an einer Grundplatte 10 angebracht. Die Grundplatte 10 ist mit der Arbeitsmaschine 4 verbunden. Zusätzlich sind zwei Hydraulikzylinder 11 und 12 vorgesehen, mit denen sich die Fräse um das Drehgelenk 8 schwenken lässt.According to the present invention, the tiller 1 is now attached to a base plate 10 via a swivel joint 8 . The base plate 10 is connected to the working machine 4 . In addition, two hydraulic cylinders 11 and 12 are provided, with which the tiller can be pivoted about the swivel joint 8 .

Das Drehgelenk 8 ist so ausgebildet, daß sich die Fräse 1 nach links und rechts schwenken lässt, das bedeutet, die Drehachse des Drehgelenks 8 ist vertikal angeordnet.The swivel joint 8 is designed in such a way that the tiller 1 can be swiveled to the left and right, which means that the axis of rotation of the swivel joint 8 is arranged vertically.

Wenn nun eine Kurve gefahren werden soll, wird die Fräse durch die Hydraulikzylinder 11 und 12 in die vorgesehene Fahrtrichtung geschwenkt. Dadurch steht die Fräse 1 immer quer zur gewünschten Fahrtrichtung und kann von vorne den Schnee der Schneeansammlung 5 aufnehmen. Es treten keine seitlichen Kräfte auf, welche die Kurvenfahrt behindern würden.If a curve is now to be driven, the milling machine is pivoted by the hydraulic cylinders 11 and 12 in the intended direction of travel. As a result, the tiller 1 is always transverse to the desired direction of travel and can pick up the snow from the snow accumulation 5 from the front. There are no lateral forces that would impede cornering.

Dabei kann die Einstellung der Neigung der Fräse 1 manuell erfolgen, oder aber durch einen Lenkwinkelsenor 13 erfolgen, der in Abhängigkeit der bei der Arbeitsmaschine 4 vorgesehenen Fahrtrichtung die Fräse 1 einstellt. Hierzu muss allerdings ein entsprechender Sensor 13 an der Arbeitsmaschine 4 installiert sein. Deswegen ist es bei gelegentlichen Einsätzen auch denkbar, daß ein entsprechender, nicht dargestellter Sensor vorgesehen ist, der mobil die Radstellung der Arbeitsmaschine 4 erfasst. Dazu kann der Sensor an der Grundplatte 10 oder der Fräse 1 angebracht sein.The inclination of the tiller 1 can be adjusted manually or by a steering angle sensor 13 which adjusts the tiller 1 depending on the direction of travel provided for the working machine 4 . However, a corresponding sensor 13 must be installed on the working machine 4 for this purpose. For this reason, it is also conceivable for occasional use that a corresponding sensor (not shown) is provided, which detects the wheel position of the work machine 4 in a mobile manner. The sensor can be attached to the base plate 10 or the milling cutter 1 for this purpose.

Für die Ölversorgung der Hydraulikzylinder 11 und 12 kann eine an der Arbeitsmaschine 4 vorhandene Hydraulik genutzt werden. Es ist aber auch denkbar, daß die Fräse 1 ihr eigenes Hydrauliksystem aufweist. In den Versorgungsleitungen der Hydraulikzylinder 11 und 12 können Überdruckventile 14 vorgesehen sein, die bei zu starker Belastung der Fräse 1 zum Beispiel durch Anfahren gegen Kanten oder dergleich ein Wegschwenken der Fräse 1 ermöglichen und so Beschädigungen derselben vermeiden. So kann beispielsweise wirksam ein unerwünschtes Abscheren der in der Fräse 1 als Sicherheitseinrichtung vorgesehenen Scherbolzen vermieden werden. Wenn die erhöhte Belastung beendet ist, kann durch einen erneuten Druckaufbau die Fräse 1 wieder in die vorgesehene Stellung zurück gehen.For the oil supply of the hydraulic cylinders 11 and 12, a hydraulic system present on the working machine 4 can be used. But it is also conceivable that the milling machine 1 has its own hydraulic system. In the supply lines the hydraulic cylinders 11 and 12 can be provided with overpressure valves 14, which allow the milling cutter 1 to swivel away when the milling machine 1 is subjected to excessive loads, for example by bumping against edges or the like, and thus avoid damage to the same. In this way, for example, an undesired shearing off of the shear bolts provided as a safety device in the milling machine 1 can be effectively avoided. When the increased load has ended, the milling machine 1 can return to the intended position by building up pressure again.

Gemäß der vorliegenden Erfindung ist es auch denkbar, daß nicht nur ein Drehgelenk 8 vorgesehen ist, sondern mehrere, die parallel zueinander angeordnet und beispielsweise über eine Zwischenplatte miteinander verbunden sind. Durch eine solche Anordnung ist eine Anpassung auch an engere Kurvenradien möglich. Es wird verhindert, daß die Fräse 1 aus dem Kurvenradius der Arbeitsmaschiene 4 herausragt. Zu diesem Zweck ist es auch denkbar, daß ein Verschiebemechanismus vorgesehen ist, der ein seitliches Verschieben der Fräse relativ zur Arbeitsmaschiene 4 ermöglicht. Dieser Verschiebemechanismus kann ebenfalls hydraulisch gesteuert ausgeführt sein und automatisch oder manuell angesteuert werden.According to the present invention, it is also conceivable that not only one swivel joint 8 is provided, but several, which are arranged parallel to one another and are connected to one another, for example via an intermediate plate. Such an arrangement also allows adaptation to tighter curve radii. The tiller 1 is prevented from protruding from the curve radius of the working machine 4. For this purpose, it is also conceivable for a displacement mechanism to be provided, which enables the tiller to be displaced laterally relative to the working machine 4 . This displacement mechanism can also be hydraulically controlled and can be controlled automatically or manually.

Desweiteren ist auch eine Kippvorrichtung denkbar, die eine Neigung der Fräse 1 ermöglicht. Auch hier kann eine Überlastsicherung zum Beispiel durch Überdruckventile vorgesehen werden.Furthermore, a tilting device is also conceivable, which allows the tiller 1 to be inclined. Overload protection can also be provided here, for example by means of pressure relief valves.

Weitere Ausführungen sind denkbar, wobei die Erfindung in den Ansprüchen definiert wird.Further embodiments are conceivable, the invention being defined in the claims.
